IMPROVEMENT m TETHERS.

Specification forming part of Letters Patent No. 174,407, dated March 7,1876 application filed October 12, 1875.

e To all whom it may concern: a

Be it known that I, SAMUEL L. BoYLEs, ,of Spring Grove, State ofWisconsin, have invented a Tether, of which the following is aspecification:

The object of my invention is to confine an animal to pasture, asillustrated in the antruck or carriage suspended from pulleys a a,

and provided with a pulley, b, to ease the friction on the wheel B, andalso provided with a pulley, c, to carry the rope, asshown in thedrawing. This carriage will, by its own weight, always remain suspendedfrom the pole A A, and can also move up and down on the pole A A, thefriction being eased by the small pulleys a a. I) is a pulley, alsosuspended from the pole A A at its upper end, and is hung by a cliploosely, so that it may at all times remain suspended from the pole, butis not intended to slide up or down the -pole.- E is a rope, to whichthe animal may be hitched, and is provided with a stop, d,

and also with a weight, 6, and passes over the pulley D and the smallpulley c of the carriage O.

It will be seen that as the animal grazes away from the tether the ropemay follow him until the weight 0 strikes the carriage O, and after thatthe carriage 0 may ascend the pole until it strikes the pulley D, thusallowing the animal to have more range of pasture than would befurnished by the rope itself if fastened to a picket, and=then, as theanimal nears the tether, the carriage will descend the pole and take upthe slack of the rope until the stop d strikes the pulley D.

The movements of the animal while grazing will also turn the Wheel B,and thus the animal will not be confined to one sp0t,'as if hitched to apicket, and the rope, by being kept off the ground, will wear longer,and also prevent frequent entanglements of the animal with the rope.

I claim as my invention- The pole A, provided with wheel B, incombination with the carriage O, pulley D, and rope E, arranged tooperate substantially as described.
